Next-generation GMC Canyon, Chevy Colorado spied together

With the debut of the next-generation GMC Canyon coming in a couple of months (in off-road-ready AT4 guise no less), it's no surprise that both it and the Chevy Colorado are out testing without the heavy coverings of early prototypes. One of our spy photographers caught examples of both trucks with close-fitting vinyl wraps. This gives us a great opportunity to see each pickup more clearly, but also to compare and contrast the designs. From the front, the GMC features a narrower, but seemingly taller grille. At the top are slender lamps. They seem to be daytime running lights, though, and below them are much larger units that will function as the actual headlights. The prototype shown seems to be one of the AT4 variants, based on the lack of a lower air dam and the opened up corners of each bumper. Small fog lights show up in the lower bumper, too. As for the Chevy, its grille is wider, and it blends into the headlights. The lights are at the top of the grille, and they seem to incorporate the actual headlights, not just running lamps. The grille mesh has some interesting detailing, and there are auxiliary lights below the main headlights. This one seems to be a more mainstream Colorado model since it still has a front air dam, possibly a Z71 model, considering the chunky tires. Not surprisingly, the two trucks are very similar from the sides and the rear. They have cabins that look lower, longer and more squared-off than the current models. The fenders look more punched out and aggressive, too. The main differentiator between the Chevy and GMC are the wheel openings. The GMC has sharp corners and the Chevy has more rounded ones, as is the case with the full-size trucks. As previously mentioned, the GMC Canyon AT4 will be revealed this summer, so likely in just a month or two. The Colorado will likely be revealed this summer, too. It's expected that it will use the turbocharged 2.7-liter four-cylinder shared with the Silverado. Naturally, it will be available with two- and four-wheel drive and a variety of trim levels including the AT4 and ZR2 off-road versions. Related video:

Leak reveals GM's 2017 heavy duty diesel trucks to get 910 lb-ft of torque [UPDATE]

UPDATE: Chevrolet officially announced specs for the 2017 Silverado HD and the rumors were true. The truck's new Duramax 6.6-liter turbo-diesel V8 puts out 445 horsepower and 910 pound-feet of torque. Chevrolet says the new motor produces 19 percent more torque and 12 percent more horsepower, while producing 35 percent fewer emissions. Overall, the new engine is a big improvement over the current motor, which generates 397 horsepower and 765 pound-feet of torque. According to Truck Trend, GM's newest heavy duty pickup trucks will pick up quite a bit more power and torque. The publication spotted a recent GM Powertrain ordering catalog that had the engine specs for the 2017 model year and managed to get some screenshots before the catalog was taken down, and they can be viewed here. The screenshots revealed that the 6.6-liter turbodiesel V8 powering the Silverado and Sierra heavy duty models will boast 445 horsepower and 910 lb-ft of torque. This is a substantial gain over the current models' 397 horsepower and 765 lb-ft of torque, and as Truck Trend points out, it exceeds the Ford Super Duty line's horsepower output of 440, but comes short of the 925 lb-ft rating. Truck Trend credits part of this output gain to the new intake system GM will introduce on the 2017 heavy duties. The intake gets 60 percent of its air from a scoop on the hood, with the other 40 percent coming from behind one of the front fenders. GM doesn't reveal horsepower figures in the press release about the scoop, but it does say the cooler air helps with maintaining the engine's output, and that the scoop does produce a ram-air affect, providing more air at speed. As we know, more air plus more fuel equals more power, but there's likely more to the power increase in this engine than only the intake.

Helicopter crashes on Top Gear Korea set while chasing Corvette ZR1

The formula of Top Gear Korea is seemingly about the same as it is everywhere else in the world, including the flagship British original: involve interesting cars in fantastical situations with charismatic hosts. That prescription has proved to be pretty reliable over the years, and has lead to some truly memorable and exciting pieces of television.
Something like that was undoubtedly what the Korean producers were after when they lined up this segment - a drag race between a Chevrolet Corvette ZR1 and an AH1 Cobra military helicopter. The planners almost certainly did not expect the filming of the segment to go quite as wrong as it actually did, with the helicopter actually crashing into the dirt after the "drag race" had been completed. Thankfully, we're told that no one was seriously injured in the crash, but the footage, in the video below, is pretty damn chilling to watch, nevertheless.
